The Moving Earth
Earth moves around the sun in a nearly circular path called an orbit.
One round trip, or revolution, around the sun takes 365 days. This is an Earth year.

The Moving Earth
As the Earth revolves around the sun, it spins on an imaginary line that runs from the North Pole to the South Pole. This line is called an axis.

The Moving Earth
The spinning motion of the Earth is called a rotation. Earth makes one full rotation about every 24 hours. As the Earth spins, it is daytime on the side facing
the sun. On the side facing away from the sun, it is night.

Earth’s Tilt
Earth’s axis is tilted at an angle. Because of the tilt, the Northern and
Southern hemispheres receive different amounts of sunshine as Earth moves around the sun.
This difference creates Earth’s seasons. EARTH’S TILT CREATES THE SEASONS!

Tropics, Circles, and Zones
Because of Earth’s tilt, the sun never beats straight down on places in the far north and south.
The line of latitude that marks the northernmost point where the sun beats straight down is the Tropic of Cancer.

Tropics, Circles, and Zones
The line of latitude that marks the southernmost point where the sun beats straight down is the Tropic of Capricorn.
Alice Springs, Australia

Tropics, Circles, and Zones
The areas between these two lines are known as tropical zones.
Tropical zones receive a lot of sunshine. They are hot year round.

Tropics, Circles, and Zones
Two other lines of latitude mark the points farthest north and south where the sun doesn’t shine at all one day each year.
On that day, night lasts a full 24 hours.

Tropics, Circles, and Zones
The northern line is called the Arctic Circle.

Tropics, Circles, and Zones
The southern line is called the Antarctic Circle.

Tropics, Circles, and Zones
The areas between these circles and the North and South poles are known as polar zones.
These zones receive little sunshine. They are cold throughout the year.

Tropics, Circles, and Zones
Between the tropical and polar zones lie the temperate zones.
Generally, in these zones summers are warm and winters are cool.
